LED che si accende anche se l’interruttore è spento? Ecco le prime soluzioni per evitarlo

💡 Have you ever seen an LED bulb that stays on even with the switch turned off? It's not a fault, but a real electrical phenomenon related to capacitive currents! When wires run close to other live wires, they behave like hidden capacitors. Even if the phase is interrupted, microcurrents are generated that activate the LED driver. In this video, we analyze the complete diagram and explain how the circuit actually closes. We also look at the most effective solutions to avoid the problem, such as the bipolar switch or the bleeder resistor. 📚 Do you want to learn the basics of electricity easily and without too many technical jargon?
